Packet Pushers - Weekly Show

On today’s Heavy Networking we talk LACP and link aggregation. While bonding two or more links together to act as a single virtual link has been done for decades, LACP and link aggregation aren't the same thing, and the distinction matters. Our guest to get into the differences is network instructor Tony Bourke. The post Heavy Networking 690: LACP Is Not Link Aggregation – With Tony Bourke appeared first on Packet Pushers.

Certifications are a part of life in IT. On today's Heavy Networking we explore preparation strategies with guest Mary Fasang.

Its about reducing the cost and complexity of DWDM coherent optical networks. Connecting the DWDM network directly to your router removes the DWDM edge equipment which simplifies operation, reduce cost,space & power while improving provisioning time. How is Juniper entering this market and what do you need to know ? The post HN687 Juniper CORA Coherent Optics Enabling IPoDWDM appeared first on Packet Pushers.

Today we’re going deep on software-defined networking for containers and OpenStack with sponsor Juniper Networks. Juniper has revamped its approach to secure networking for telcos and telco cloud-delivered services with Juniper’s Cloud-Native Contrail Networking or CN2 software. CN2 lets you automate the creation of network connections for containers and for virtual machines while also providing routing, security, segmentation and isolation of workloads. Our guest and guide into the guts of Cloud-Native Contrail Networking, hereafter referred to as CN2, is Nick Davey. Nick is Director of Product Management for SDN and Telco Cloud technologies.

By some estimates, 50 to 70 million tons of e-waste is generated every year, and that number is growing. When sent to landfills to be buried or burned, e-waste can leach toxic chemicals into soil and air. On today’s Heavy Networking, we’ll look at options for responsible disposal of IT gear, including repurposing it on site, reselling or donating it, and working with e-cycling companies. The post Heavy Networking 684: What To Do With Your E-Waste? appeared first on Packet Pushers.

On today’s Heavy Networking we have a conversation about monitoring, visibility, and observability with sponsor Palo Alto Networks. More specifically we’ll dig into Palo Alto Networks’ Autonomous Digital Experience Management, or ADEM product, and how Palo Alto Networks is integrating ADEM with AIOps. The post Heavy Networking 683: Palo Alto Networks Integrates AIOps Into ADEM For Faster Remediation (Sponsored) appeared first on Packet Pushers.

If you’ve shied away from network automation because you’re a network engineer not a coder, fear not. There are network automation approaches that can help you get needful work done and don’t require a computer science degree. On today's Heavy Networking we talk with sponsor BackBox about its practical approach to network automation and dive into use cases including network OS backups and compliance.

Modern F1 racing is bathed in data. Real-time vehicle telemetry. In-car video feeds. More video from camera crews and drones. Live streaming. All of this and more needs a network. On today's Heavy Networking we speak with Formula 1's David Ramsden, Senior Network Engineer; and Lee Wright, Head of IT Operations, to get the inside track on building the networks that support F1 races. The post Heavy Networking 681: Under The Hood Of Formula 1 Networking appeared first on Packet Pushers.

It's common for SD-WAN vendors to offer monitoring as part of the solution, but leaves the question … how do I monitor the rest of the network? Today’s sponsor Broadcom offers digital experience monitoring that is independent of the underlying WAN infrastructure. We explore how it works with guest is Jeremy Rossbach, Chief Technical Evangelist, NetOps by Broadcom.

Today's Heavy Networking explores the challenges Wireless ISPs (WISPs) face when bringing services to locations without a lot of fiber in the ground. Those challenges include lining up radio antennas, maintaining mountaintop gear, wild horses, network and routing designs, and more. Our guest is Bradley Thompson, Senior Network Engineer at SkyFiber Internet. The post Heavy Networking 679: Mountaintop Networking And Long-Haul Wireless appeared first on Packet Pushers.

On today's Heavy Networking we dive into the frameworks commonly used by service providers to tackle network slicing and traffic engineering challenges. We'll also talk their pros and cons, and the approach that Cisco is seeing its customers adopt as providers create virtual networking products for their customers. Cisco is our sponsor for today's show. The post Heavy Networking 678: How Cisco Enables Orchestration, Network Slicing Across Service Provider Networks (Sponsored) appeared first on Packet Pushers.

You ever want a group of fellow networking nerds to hang with once in a while? The US Networking User Association might be exactly what you’re looking for. With local networking user groups popping up in various places all over the US and soon other countries, the USNUA is fostering community and knowledge sharing for networkers everywhere.

Fortinet is a security vendor most of you have heard of. But if all you think of when you hear the name “Fortinet” is firewalls, well yeah, but you should think more broadly. On today's sponsored Heavy Networking we're going after the work-from-anywhere challenge with Fortinet’s Zero Trust Network Access (ZTNA) and Secure Access Service Edge (SASE) tech, all of which is baked into FortiOS. If you’re running a FortiGate, you’ve got these capabilities already. The post Heavy Networking 676: Implementing ZTNA And SASE With Fortinet (Sponsored) appeared first on Packet Pushers.

Today’s Heavy Networking podcast explores the concept of NetDevOps with sponsor Itential. The idea behind NetDevOps is to advance your network to the point where it’s self-service; that is, the network you operate can be consumed the way public cloud services are consumed. Our guest is Itential co-founder & CTO Chris Wade. The post Heavy Networking 675: Enabling Self-Service Automation & NetDevOps With Itential (Sponsored) appeared first on Packet Pushers.

You know all those Apple and other IoT devices connected to your wireless network? Lots of them run apps that discover services on your network via multicast DNS (mDNS). All of that mDNS traffic can have a significant impact on your WLAN’s performance. On today's Heavy Networking we talk with guest Bryan Ward who has actually measured the impact of mDNS on a production wireless network to see what would happen if he let mDNS traffic run wild. The post Heavy Networking 673: Multicast DNS Gone Wild On Your WLAN appeared first on Packet Pushers.

Lots of folks suffer from impostor syndrome. Tech is complex--how could you know what you’re doing? And yet, many of us are responsible for incredibly complex IT systems. Fake it ‘til you make it, right? To handle the cognitive dissonance of impostor syndrome, we overcompensate. In doing so, we pay a personal price. Today's Heavy Networking guest is Matt Vitale. He's here to share what he's learned about coping with and overcoming imposter syndrome. The post Heavy Networking 672: Overcoming Your Imposter Syndrome appeared first on Packet Pushers.
